Simply put, this game is "the awesome". However, like any other game, Rainbow
Six Vegas has its share of rough spots -- some which are difficult
to overcome on harder difficulties. Plus there're preset ambushes you just
might not like walking into.

Try IGN's strategy guide for Rainbow Six Vegas' single player
campaign (applicable to co-op) and get by all the toughest spots in each
of the rooms you will face. Good luck soldier. You will need the assistance!
